Karratha (crater)
Karratha is an impact crater in the Memnonia quadrangle of Mars. It was named after the town of Karratha, Western Australia, in 2021. Karratha lies within the larger Dampier, which is south of Burton crater. The crater is thought to be around 5-10 million years old. It has been suggested to be the source crater of the Martian meteorite Northwest Africa 7034 Northwest Africa 7034 is a Martian meteorite believed to be the second oldest yet discovered.Associated Press (January 4, 2013)Mars meteorite 'Black Beauty' contains most water of any found on Earth, say scientists.''The Guardian'' It is estimated ....

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...

Karratha, Western Australia
Karratha is a city in the Pilbara region of Western Australia, adjoining the port of Dampier. It was established in 1968 to accommodate the processing and exportation workforce of the Hamersley Iron mining company and, in the 1980s, the petroleum and liquefied natural gas operations of the North West Shelf Venture. As of June 2018, Karratha had an urban population of 16,708. The city's name comes from the cattle station of the same name, which derives from a word in a local Aboriginal language meaning "good country" or "soft earth". The city is the seat of government of the City of Karratha, a local government area covering the surrounding region. Geography Karratha, an isolated city, is located approximately north of Perth and west of Port Hedland on the North West Coastal Highway. It is at the south central end of Nickol Bay, which has had settlements on the bay since the 1860s. The city is roughly rectangular in layout and is located on flat land adjacent to Nickol Bay. ...

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Memnonia Quadrangle
The Memnonia quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Memnonia quadrangle is also referred to as MC-16 (Mars Chart-16). The quadrangle is a region of Mars that covers latitude -30° to 0° and longitude 135° to 180°. The western part of Memnonia is a highly cratered highland region that exhibits a large range of crater degradation. Memnonia includes these topographical regions of Mars: * Arcadia Planitia * Amazonis Planitia * Lucus Planum * Terra Sirenum * Daedalia Planum * Terra Cimmeria Recently, evidence of water was found in the area. Layered sedimentary rocks were found in the wall and floor of Columbus Crater. These rocks could have been deposited by water or by wind. Hydrated minerals were found in some of the layers, so water may have been involved. Many ancient river valleys including Mangala Vallis, have been found in the Memnonia quadrangle. Mangala app ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burton (crater)
Burton is an impact crater in the Memnonia quadrangle of Mars. It is 123.0 km in diameter and was named after British astronomer Charles E. Burton; the name was approved in 1973. It has a central peak. Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak. The peak is caused by a rebound of the crater floor following the impact. Cobres crater is northeast of Burton, and Marca crater is to the northwest. Mangala Valles is to the east. In December 2021, three craters immediately south of Burton were named. These are Karratha, Khujirt, and Dampier. Karratha is within Dampier.

Martian Meteorite
A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. , 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. The largest complete, uncut Martian meteorite, Taoudenni 002, was recovered in Mali in early 2021. It weighs 14.5 kilograms (32 pounds) and is on display at the Maine Mineral & Gem Museum. There are three groups of Martian meteorite: shergottites, nakhlites and chassignites, collectively known as SNC meteorites. Several other Martian meteorites are ungrouped. These meteorites are interpreted as Martian because they have elemental and isotopic compositions that are similar to rocks and atmospheric gases on Mars, which have been measured by orbiting spacecraft, surface landers and rovers. The term does not include meteorites found on Mars, such as Heat Shield Rock. History By t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northwest Africa 7034
Northwest Africa 7034 is a Martian meteorite believed to be the second oldest yet discovered.Associated Press (January 4, 2013)Mars meteorite 'Black Beauty' contains most water of any found on Earth, say scientists.''The Guardian'' It is estimated to be two billion years old and contains the most water of any Martian meteorite found on Earth. Although it is from Mars it does not fit into any of the three SNC meteorite categories, and forms a new Martian meteorite group named "Martian (basaltic breccia)". Nicknamed "Black Beauty", it was purchased in Morocco and a slice of it was donated to the University of New Mexico by its American owner. The image (shown on the right) of the original NWA 7034 was photographed in 2012 by Carl Agee, University of New Mexico. Discovery and naming The meteorite was found in Rabt Sbayta, Ghredad Sabti region, Western Sahara, in the Sahara Desert in 2011, and was purchased in Morocco by a meteorite dealer who sold it to a collector in the United States ...
